GB to ICS/JB - Galaxy S II Q&A, Help & Troubleshooting

Hi everyone!!
I bought a S2. Installed villain Rom 3.0 with provided kernel. Now I want to install a custom ICS/JB rom.I searched on youtube and other XDA threads and found that I need to upgrade the bootloaders and other stuff and need to install ics through ODIN. Is that correct? or I should just download a custom ICS/JB and install it thru CWM as normal?

Yes, just install like normal. Or you can upgrade boot loader, phone, pda, csc. So do what you want.
Send form Galaxy S2. But I don't have it :-\

I suggest you leave the bootloader as it is if you dont know what you are doing

Just pick a rom and follow the install instructions.

[Q] Upgarde to froyo via phone itself

I got galaxy I5503 with eclair 2.1 and i still got a stock rom. I just want to upgrade my g5 to froyo 2.2 via my g5 itself not using any kind of help from pc,Is it possible..???
if yes than plz answer the query cuz im very eager to try new custom roms.
Stock rom?
Hey dude.I think you cant do that without using a PC,as you need at least to flash clockwork mod.And one more thing,as you are saying that you are on stock rom please visit the below link and backup your rom.
You need to get ClockWorkMod on your phone first. To do that, you need a pc anyway.....
you will need your pc... for official updates or unofficial ones.
for official froyo you will need KIES and download thru it... if you want to run CM7 or any other rom you will also need Odin to flash ClockworkMod Recovery, and then you can install any other G5 rom you want.

[Q]Stock ROM

Recently , i have been watching some Cyanogenmod 9 ICS 4.0.3 ROM video and it seems to be cool. Well my question is if i flash the Cyanogenmod ROM , can i re-flash the stock ROM that i had?
And is it safe to flash a custom rom?

Cool as in not overheating ???
a wipe and flash of stock rom will remove custom rom .
Root and custom roms void warranty and have a slight risk of bricking the phone .
But are usually recoverable .
You need to read the faqs and guides and understand the CM9 instuctions first .

to flash cynogen rom first u have 2 root ur phone please find the thread in original devlopment section regarding the same
u can reflash ur stock rom by dwnld the releavant .tar file adn flash the same thru odin
You can re-flash the stock rom, but just be sure to know which one is your stock rom. Go to settings, about phone and record the info there to be safe. Also back up your current rom using CWM.
There are always some risk in flashing a rom. Some people dont read instructions and cause problems on their phone, some people flash a rom not built for their phone (i9100 VS i9100G), etc.
Yeah i have rooted my device with cf-root. Thanks guys , i'll read some guides about cyanogenmod and flash it.
If your are currently on GB stock rom, Cyanogenmod developer recommends to install ICS bootloaded first,
You should be able to reflash your Stock ROM veriosn from ODIN, as well as custom roms from CWM...
What is bootload? o.o
My current firmware is ICS LP7

No they say to have below some specific ics boot loader, no mention of upgrading your gb boot loader, unless they changed it.
Plus I yet to had any issues with the latest ics or gb bootloaders..

I think he meant boot loader.
But since you already have ICS, you won't need it. Just take the latest CM9 nightly (or ROM based off it), and flash (you'll have to wipe cache data and dalvik too eventually). Make sure you make a full backup of your current stock ROM through CWM as well.

I refer this guide actually : http://forum.xda-developers.com/showpost.php?p=20841817&postcount=1
I dont know its outdated,
as others are sharing their experiance that you could flash CM9 straight away from your CWM since you are already on LP7 with ICS Bootloader.....
I don't get it... What is a bootloader?. I mean when i flashed with ICS LP7 i didn't put a file on bootloader. I just loaded the PDA .tar file and flashed it..
Soo that means that i have to reflash the stock rom with bootloader?

I dont know the ICS package you flashed had an ICS Bootloader already...
I just gave you the link for Original CM9 developers guide...
Just wait for others recommendation who have already flsahed CM9 from CWM....
Hmm thanks . But i have read in the guide that i can flash it with odin , do i still need the bootloader?

Going back to official firmware?

Hello.
I have had a GS3 for a few months now and a few weeks ago my friend showed me how to install the polish jellybean update for my phone (I don't have a polish gs3 but he said it was safe to do ) and it was pretty easy.
I have decided to use a custom rom now. I have already rooted my phone but before I install a custom rom I was wondering how easy it is to go back to the polish version that I have downloaded if I don't like it.
Thanks and hopefully this is the right part of the forum to post this in.

Thank you. If I want to try out different custom roms do I have to go back to official firmware first or can I just install a custom rom over another custom rom?
Hi,
You can flash a custom rom without going back to the "original version" (stock rom that came installed in your GS3) - Just keep in mind that you must do a full wipe in your device (data/cache and dalvik).
You just need to flash the CWM via odin and then flash the custom rom via CWM.
You just need to follow this instructions here (http://forum.xda-developers.com/showthread.php?t=1695238)
And than follow the instructions of your favorite custom rom to install it.
Cheers

OK, but he doesn't need to go back to the stock rom before flash another custom rom. To try another custom roms he only needs to do the wipes and follow the instructions of the custom rom to install it.

First...to which ROM is the best...depends on you're style and device. All devices aren't equal...even when they are the same variant.But I like the 4.3 ROMs.Look at my SIG to see which one I'm running today...Lol.
Now..on to you're rooting. You most definitely need to update to 4.0.4 ICS..I have a guide after you're on that version so you can root and stay stock or flash a custom ROM.But you need the ICS boot loader to flash almost all of the new jelly bean ROMs, if not all of them.I believe when you do the official update from kies it will install that boot loader.( never had to as my device was on 4.0.4 unrooted ).
Back up you're tab to you're PC before you go updating..The update might wipe sdcard, not sure. And in case the update goes side ways on ya.
Let me know if you need any help.

Getting to the safe side , the best is using traditional flashing to ICS then to JB.
I am currently rooted for HC.The ordering , I need to flash it to samsung ICS first ? which mean , I need to unroot my device ?
Or I can just flash to custom roms ICS ?
Currently , stuck at this point.Which is the correct procedure ?
Flash stock ICS first using Odin first. Then you can flash to any version you want.

No. Just flash it with Odin. Don't use that ROM. That is a modified version. Download the stock ROMs at www.sammobile.com.

i9100 Rooted but no CWM

Hello everyone, greeting from Turkey!
First of all im a newbie for android rooting and romming etc. I ve always used stock roms since ive got this phone. Now Im running a I9100 (int.) with stock Turkish 4.1.2 (XXLS8) on it and i ve rooted it via superuser.zip with my stock recovery.
What i want to do is to install CWM and want to flash a RELIABLE and Long Battery life rom. Are there anyways for me to install a CWM without using odin (via stock recovery). And can you please suggest me a good rom for daily usage. (i want to use vanilla android btw [just like nexus]).
Thank you for your helps.
I don't know much about roms/kernels for the international version, but you will need to flash a stock kernel with cwm and then just choose a rom from your development thread and follow the instructions, don't forget making backups and reading a lot, you can start from flashing cyanogenmod.

As i said i dont know about international version kernels, but it should have a tag like "stock kernel" or something like that if its for stock, just install it and you will have cwm, if its not stock it wont be installed anyway.
